The hitch harness kit parts with the “A” level are for brand new installs where a trailer hitch
harness has never been installed and should not be used for the recall repair. The parts
listed in the parts information below are for the recall only, where a vehicle had the
original part installed.
Safety Recall – 2023 CX-50 Trailer Tow Hitch Harness May Detach
CONDITION OF CONCERN: On certain 2023MY CX-50 vehicles with the installed Mazda Genuine
Accessory trailer hitch harness, the harness may loosen or detach, causing insufficient clearance to
underbody components. The detached trailer wire harness could become damaged due to contact
with the vehicle’s exhaust components or road debris while driving. A damaged harness can cause the
lights and/ or braking of a connected trailer to become inoperative, increasing the risk of a crash. Both
the 4-pin and the 7- pin harnesses are affected.
OUTLINE OF REPAIR: This repair is to remove the old Trailer Hitch Harness and install a new updated
harness with a different routing than the original factory, dealer or customer installed harness.

Mazda is concerned about your safety, and we encourage you to contact any authorized Mazda
dealer to schedule an appointment to have your CX-50 vehicle repaired as soon as possible. You

August 5, 2022: MTM Logistics Quality regular inspection detected five vehicles at Mazda Port facilities with peeling or detached wire harness adhesive mounting brackets. Mazda began to investigate the concern; installation of the harness was halted to prevent any potential further outflow of the concern into the field. August 15, 2022: Inspection of field units with accessory harness kits installed by dealers did not show recurrence of the peeling/detached adhesive.
September 2022~December 2022: Mazda conducted investigations of the concern to assess root cause, potential effects on any field units with the condition, and review of actual field conditions.
January 2023~Middle of February 2023： Mazda did not receive any field reports related to this concern through this period. However, Mazda continued to identify the total population of potentially affected vehicles in North American markets.
February 22, 2023: Mazda held a Quality Audit Committee meeting to review all available information to date and, out of an abundance of caution, determined to conduct a proactive field action on certain MY 2023 CX-50 vehicles equipped with accessory trailer hitch wire harnesses.

Description of Remedy :
Description of Remedy Program : Owners will be notified by mail and instructed to take their vehicle to a
Mazda dealer.
Dealers will rework affected units using an improved trailer hitch harness kit.
Mazda was able to identify 311 VINs with trailer hitch harness kits through internal systems. However, accessory kits are generally not traceable to unique VINs. For those trailer hitch harness kits that could not be matched to a specific VIN, Mazda will ask dealers to attempt to make contact with original purchasers to notify them of the concern. Dealers will be given copies of owner letters to forward to purchasers. A reimbursement program will not be offered as subject vehicles are under new vehicle warranty coverage.
